ADDRESSING .MACHINE.

Application filed June 29.

To all whom it may concern:

Be it known that I, HERMANN DnU'rsoH, a citizen of the German Empire, residing at Berlin-Lichterfelde, Germany, have invented. certain new and useful Improvements in Addressing Machines (for which I have filed application in Germany, Sept. 6, 1915, Patent No. 312,926), of which the following is a specification.

My present invention relates to addressing machines in the case of which the printing lever, supporting the printing pad, is at the same time used for feeding the platens for- '*ard. One particular object of my invention is to afford the possibility of skipping certain of said platens at will, i. e., preventing them from entering into action in spite of the fact of their being fed forward continuously. The means hitherto employed to this end involve numerous drawbacks. Thus, if a covering sheet be placed across the platens to be skipped during the printing, the ink ribbon will be needlessly worn off. Again, if a disconnectible coupling be interposed between the printing lever and the platen control lever, then it will be found that, not to mention the considerable increase in the prime costs which this will occasion, shocks and an intense wear will be unavoidable.

The present invention, an embodiment of which is shown by way of example on the accompanying drawing, is intended to obviate the above-indicated drawbacks.

Fig. 1 is a sectional view along line 0-(Z in F 2,

Figs. 2 and 3 are sectional views along line 61,-?) in Fig. 1, of the device in two different working positions.

The printing pad 2 moves within a vertical slot, open at the bottom, formed in the 1920. Serial No. 392,882.

support 9, said pad 2 being impelled by springs 16, 16 against a roller 1 lodged at the end of the slot. One extremity of this roller supports a lever 18, and is moreover provided with recesses 15 in which ribs 41 fixed to the printing pad 2 are adapted to enter.

During the printing operation, the roller 1 together with the printing-pad 2, assume the position shown in Fig. 2.

If it be now desired to skip, i. e., not to print off a platen fed forward by the action of the printing lever, then by means of lever 18, roller 1 is so turned that, impelled by the action of springs 16, the printing pad 2 will come to lodge itself by aid of its ribs in the recesses 15 of the roller. The result will be that, on the printing lever being lowered, the pad will not be able to attain the ink-ribbon, and that consequently no printing will take place.

The roller 1 does not bear up directly against the end of the guide slot formed in the support 9, but against two screws 17, or other adjusting devices, arranged at the end of the said support. By means of these screws, the roller 1 may be properly shifted into the true plane required for the printing operation.

1 claim:

In a device of the kind. described in combination, a printing-pad support, a print ing-pad movable relatively to said support, springs serving to press said pad against said support, a cam shaft inserted between said support and said pad and setting screws in said support bearing against and allowing to adjust said shaft.

In testimony whereof I affix my signature.

HERMANN DEUTSCH.
